Yeah, the cells in your battery are shot. They end up having just enough charge in them to let you make it home, and then start again right away when you shut it off. If you come back to it a few hours later and whatnot, and it won't do anything, then it's shot. You should also notice that your lights will flicker and the fan for your HVAC will run slower until you put up the RPM's via the accelerator. This will be an indication that your alternator is trying to run everything on the car AND charge a battery that keeps discharging or won't hold a charge.

I had a similar problem with my car when my original battery wore out. If I drove from my house to the CT down in Pembroke, it would build enough charge on the drive on the highway to pass load tests and whatnot every time. So, I had the car at a stereo shop getting something done to it (checking why the headlights were flickering at idle with the capacitor ON on the stereo), and it almost didn't start after we were done. I got a new higher ouput battery (up to 800 amps from the factory 500 that was in it), problems solved.

If your car is an 02 or older, you may as well replace the battery, and then you can start a process of elimination that way. But I'm certain the battery is your problem.
